Mine is all in for the final time. I ended up using the 1.5 degree spacer to get the pinion angle where I wanted it.
Also I weighed the assembled hybrid halfshafts against the TurboII halfshafts. The hybrid halfshafts are about 4 lbs heavier each. That makes the weight difference about a wash for this swap.
Plenty of thread contact with Turbo 626 outers and no washer. Axle is flush with the nut.
Looking down the back of the hub, you can see where the boot clamp sticks out. The DTSS bushing is already beveled and the clamp clears.
Basically ready to go. I ended up needing a slightly longer sublink (about 1/4 inch) with my solid front mount spacer. I installed a Ground Control unit today and it fits great with plenty of clearance around the diff housing. I also installed the small CV boot clamps after I took this. I removed the axle seal covers from the Explorer inner CVs. I don't plan on taking the car out in the mud or dirt so I figure those weren't needed.
Soild spacer installed
Driveshaft clearance - the weight is about 1/4 in from the subframe - Whew that was close
